Bondtech Heat Break Kit for Prusa Mini

The Bondtech Heat Break Kit for Prusa Mini is a bi-metallic heat-break made by Slice Engineering for the Prusa Mini addresses and solves the heat-creep issues of all materials we tested.

The adjusted length of the PTFE tube also prevents clogs to form between the tube and the heat-break.

Included in this kit:

• 1x Copperhead P Mini heat-break
• 1x 32.8mm 2/4 chamfered PTFE tube
• 1x Silver based thermal paste bag [14118]

Recommendation

We recommend to use the included silver based thermal grease to properly fit the P Mini heat-break in the Prusa Mini’s heat-sink.

Notes on twisting the heat-break

To address the heat creep issues the design features a narrow steel throat with thin walls. When removing the heater block or changing nozzles, caution is required.

Before removing the heater block from the heat-break (or vice versa), heat-up the nozzle, hold the heater block and release some tightening pressure from the nozzle. Let the whole group cool down. After, you can simply unscrew the heat-break from the heater block.

To remove or replace a nozzle, never forget to secure the heater block before twisting the nozzle.
